Suggestion Berserker:

2/21/12 - level 20, level 6 Berserker - after 12 attempts, i finally beat it (barely). My Berserker is level 6 with 685 HP, 44 attack, 5 def, only spells are shattering strike and footmen spell. Used the following formation, ended up being my hero attacking castle with help from 2 wolf riders and shaman for half of the castles HP before they got killed, against cpu's 2 hero's...spawned the crap out of the spells...the footman spell kept the cpu's heros from doing damage quicker than me...i'm thinking that a back line of footman instead of archers might work too since they can withstand the spells better, my archers didnt stand a chance...

Suggestion Berserker: Level 20 Berserker.

I lost all footmen and archers, most mages, and my hero. I did not lose any wolfriders. I did not use any spells either. After clearing the enemy troll cyborgs my wolf riders made quick work of everyone else, even the Jack Brothers.

I had to keep my hero the more i can, so we need Priest but they are weak so i added 3 lines of Priest to replace the dead Priest during fight. Footmen+Ninja are a bit stronger/faster than Footmen+Troll

I focused SStrike and FBlast in front of my heroe do kill faster in front of me, i used FSpirit maybe 2 or 3 time max because during summoning my heroe doent hit so it is a waste of time for Berserker.

By Lord Chapo ;)

Confirmed by BigDick$ : I had higher losses, but probably just used my spells differently.

Edit Lord Chapo : Maybe you could try Wolf instead of 2xNinja because Wolf has same HP but are stronger.

breakdown: i have tried with foot/troll combo (no need to try knights with Behemoth) the DPS is very good but the cloth trolls just dont last long enough to eat through the troll borgs... full footmen front rows didnt do it as only one line is attacking + one row of wolf DPS from the back...then tried full mage (very expensive) all 4 rows fell and we havent even touched the enemy heros. Then i used ninjas...and 4th row cloth (mages)...light armour good Vs heavy piercing from the borgs...can hit adjacent and second row targets at once..but very low DPS..but what do you know..it worked (some what)but you MUST have the mage for eating up the heavy armour on the Borgs ..it bought me enough time for my hero to eat through to the castle wall and won with a bypass rather than an enemy wipe. two enemy heros reached my castle wall buti was there way earlier with my hero..one clr...and one mage 2 wolves doing DPS.

must admit if i got to do it again it may NOT work. i was lucky to have one clr left behind me due to the AOE splashes from the Archangels...if that last clr was gone we wipe...Hero break-through is the only way for Behemoth users. so this is my breakdown and contribution to this task. Hope it works for you Moth users too :) Cheerio.

ps : hope someone can be bothered to post a successful attack that uses post lvl 21 units like iron wheels and borgs to prove its really all worth it!...

Destroyed top Beserker and a Mage last, so possibility of destroying caslte if all else fails.

Confirmed the above with Succubus after all of the other suggestions failed. I have Blue Blast and Footmen Spirit, and the key was definitely to use both spells as quickly as possible. Survived with Hero, one Wolf, one Shaman, each side attacking the castle. The footmen distracted the remaining Hero often enough to stay ahead on attacking the castle.

Losses: Everthing but Hero, one Priest and one Wolfrider. The key is to spam your defense Spells all the time. At the one hand there is a chance that the enemy heroes cast their spells at your "ghosts", on the other hand you prevent them from attacking your castle to early. My Hero survived very closely.
(succubus) by Spavia

Note: The Priests were useless as the Archers never got attacked. Therefore, if you have higher level Wolf Riders than Archers, I suggest you switch the Priest/Archers out for Wolf Riders. I only use Archers for killing the Mages, but Wolf Riders are more effective against the enemy Heros. If you feel that the Mages will die, though, the Archer + Priests will survive better than a Wolf Rider would.

Explanation: The Footmen are obviously there to tank. The third row is Trolls because by the time the Footmen all die, the Cyborgs should be dead as well, and the Trolls will tank all the magic attacks and should be able to do serious damage or even kill the first row of Mages. The Wolf on the bottom row is there to kill the Archangel, which should not be a threat.

Just like all the previous Jack Brother battles, the Succubus has 4 Shamans behind her to ensure that she kills the enemy heros ASAP since her damage is not reduced on their armor unlike normal units. DO NOT CAST ANY SPELLS. Casting spells takes a very long time and since she has a huge Shaman boost it will actually ruin her damage (Unless you have some 400+ Mojo spell equipped). With the Shamans she will quickly tear through the Mages and enemy Heros, hopefully before they destroy your mages.
